Abstract

A scanning system and method scan an area of interest. The scanning system may include a first scanner that deflects a light signal. The light signal that is deflected by the first scanner is output as an initially-deflected light signal. A second scanner receives the initially-deflected light signal and deflects the initially-deflected light signal. The initially-deflected signal that is deflected by the second scanner is output as a subsequently-deflected light signal.
